"SPARK -ARRESTER.

SPEOIFICATION forming-"part of'Letters Patent No. 264,501, datedSeptember 19, 1882.

Application filed May 15,1es2. (Nb model.)

To all whom it may concern Be it known that 1, DAVID WISER, of the cityof Plymouth, in the county of Marshall and State of Indiana, haveinvented a newand useful Improvement in Spark-Arresters, of

tion and specification. V Y

My invention relates to a process of catchin g and arresting the sparksand cinders which usually escape from the smoke-stack of locomotive andstationary steam-engines, thereby preventing all danger from settingfire to any combustible material in the vicinity of such engines. A

The drawings attached hereto and signed by me show the principle of myinvention, and the same are hereby made a part of this specifioation.

Figure 1 in said drawings is a transverse vertical section of the deviceembodying my invention. Fig. 2 is a front view of the same, showing theposition of the wire screen in the breech of the smoke-stack and themanner of constructing and attaching the same.

Similar letters of referenceindicate like parts in said drawings.

Letter A in said drawings represents a portion of a section of anordinary flue-boiler of a steam-engine.

Letter B represents the breech of i a smokestack of such boiler.

Letter 0 represents the smoke-stack.

Letter D represents the wire screen in position in said breech whenoperating as a sparkarrester.

Letter E represents the curved deflector or guide which directs thesparks and cinders into the cinder-box.

Letter F represents the mouth or orifice in the face of the breechthrough which the cinders pass into the cinder-box.

Letter Gr represents the cinder-box, constructed of sheet-iron or otherproper material. 1 Letter H represents the partition, extending entirelyacross the cinder-box and downward at some distance below the mouth F.

Letter I represents the vent-pipe, conncctin g the cinder-box with thesmoke-stack and enterin g the smoke-stack some distance above the upperend of the cinder-box.

Letter K represents the stays, riveted to the inner sides of the breech,which prevent the :screenfrom being bent or curved by the draft.

Letter L represents the handle to the screen, by which it ismoved-backward and forward.

My invention consists of the arrangement of the wire screen D, hungonhinges at'the upper end, with the curved deflector-E, and thecinder-bo'x G, and themouth F, and the vent-pipe I, substantially asshown in the drawings; and the manner of the construction and theoperation of the different parts of my invention are as follows:

The screen D is of wire-cloth or perforated iron, and cut to exactly fitin the space assigned for its work in the breech.

The deflector E is of sheet-iron, slightly curved, and is a continuationof the screen, extending across its entiretop, and is firmly riveted tothe side of the breech.

The mouth or orifice F is a narrow opening across the face of thebreech, through which the deflector E directs the sparks and cinders.

The cinder-box G is of sheet-iron or other proper material, of anyrequired size. It is riveted to the face of the breech and the jointsclosed so as to be as nearly air-tight as possible. A door or slideopens in the bottom, from which the ashes and cinders are emptied whennecessary. Across the box is the hanging partition H, and from the topof the box is the sheet-iron vent-pipe I, connecting the box with thesmoke-stack. This pipe is of any required size, but should be ofsufficientcapacity to carry freely the heated air and gases that passthrough the mouth Finto the cinder-box.

These several parts, being in place as shown in the drawings, operatesubstantially as follows: The powerful draft of the smoke-stack draws agreat quantity of live sparks and cinders from the fire-box through theflues up-the breech. They strike against the slanting side of thescreen, and, carried by the ascending current, theyglide up its surfaceuntil they strike against the solid curved top or deflector E, by which,with some aid from the draft through the mouth F, they are carried intothe cinder-box Gr. The partition H guides them down toward the center ofthe box, where they are out of the line of the draft, and they drop tothe bottom and burn to ashes. The heated air, gas, and smoke that enterthe cinder-box F are drawn through the connecting-pipe I into thesmoke-stack, and this draft aids materially in carrying the ciudersthrough the mouth F into the cinder-box.

In wet weather, when the condition of the atmosphere is such that thedraft is lessened, the screen may be pulled to the front side of thebreech and there held, thus giving free draftthroughout the entirelength of the breech and smoke-stack, and in case the screen itselfshould partially clog with ashes and cinders it can easily be cleared byshaking it.

Having thus described my invention, what I claim as new, and what Idesire to secure herein by Letters Patent of the United States, is asfollows:

1. In spark-arresters the wire screen D, or its equivalent, hung onhinges and extending diagonally across the inner space of thebreech,substantially as shown and described.

2. In spark-arresters, the cinder-box G, with partition H and theconnecting vent-pipe I, arranged and operating substantially as shownand described.

3. In spark-arresters, the combination of the screen D, the deflector E,the mouth or orifice F, the cinder-box Gr, partition H, and ventpipe I,with the breech and smoke-stack of a steam-engine-boiler, allconstructed, arranged, and operating substantially as shown, and for thepurposes set forth.

In testimony whereof I have hereunto set my name in the presence of twosubscribing witnesses.

DAVID WISER. In presence of- A. O. (JAPRoN, CHARLES RICHARDSON.
